Design and investigation of cooling system for high-power LED luminaire

摘要

This paper is concerned with development of cooling system for high-power LED luminaire, including design, simulation, production and investigation. Dimension, shape, and topology optimization algorithms and their program realization are developed with the use of MathCad. Thermal design by Comsol Multiphysics showed that the system on the base of heat pipes is the most effective system for cooling of high-power LED luminaire. The numerical simulation was employed to valid the designed-in engineering solution of cooling system for high-power LED luminaire under elevated temperature operating conditions and different orientation in space. In accordance to simulation data cooling system on the base of heat pipes is designed. Theoretical results are well validated by experimental data and numerical simulation and can be widely utilized for designing of cooling system related to various LED products. (C) 2020 Elsevier Ltd.
